Applicatiouiled February I4, 1901.V Serial No. l7,213. (No model.)` I iTo. all whom t may concern:

Be it known-that I, GARLETON W. NAsoN, a citizen of the United States,residin-gat New York, county-of New-Yorloand Stateof New York, haveinvented certain new and useful Improvements in Condensing Apparatus,fully described and represented in the following specification and theaccompanying drawing, forming a part of the same.

My invention relates to an apparatus for cooling or condensing gas, andis intended especially for use in that class of condensers forice-making machines for cooling or liquefying the hot or compressed gascoming from capacity to machines using the device with l i and throughthe coils successively `from the Alowest coil upward through the series,the

less power required to accomplish the work and to avoidthe strain upon'the condenser pipes and joints which results from large differences oftemperature between the water and gas. i

My improved apparatus in its preferred form consists of a plurality ofcondensing-coils arranged one above the other and in which the gaspassesA downward through each coil coils being cooled by sprinklingcooling-water or other liquid upon the top coil, from which the coolingliquid passes down over the'lower coils. Thegas thus passes through eachcoil in the same directionas the condensed liquid, which is important insecuring a high eiiiciency, and the same water is applied successivelyhto thel diiferentqcoils, first upon the coldest coil and thensuccessively upon the hotter coil or coils, so .that the gas is cooledgradually by applying colder water, which secures a very efficientcondensing action without wide dierences of temperature Vbetween the gasand cooling liquid, while the amount of cooling-water required isreduced to a minimum. In accordance with my invention, therefore, theliquefied atoms of the ygas assembled `by the act of condensation thecoils in the same direction as the gas containing them, while at thesametime the condensing-waterfis so distributed over the coils that thecooler water meets the cooler gas and the warmer water the hotter gas.

In the accompanying drawingl I have illustrated a gas cooling orcondensing apparatus embodying my invention in one of its pre.

ferred forms as applied in connection with two coils, and thisconstruction will now be described and the features forming thelinvention then specifically .pointed out in the claims'.

In the drawing, A A are the two coils, through which the gas passessuccessively, these coils preferably being similar single coils, asshown, arranged one above the other and exposed to the atmosphere; B,the liquidspray pipe above the coil A; C, a drip-trough below the coils,and D a receiver for the liquid condensed from the gas. As indicated bythe arrows, the gas enters the lower coil Athrough pipe l, passesdownward through the coil A to the bottom convolution, and then throughpipe 2 to chamber or separator 3, from which any liquid condensed in thelower coil passes to the receiver D through pipe 4, while theuncondensed gas passes upward through pipe 5 to the top convolution ofthe upper coil A', then downward through the coil A and through pipes 46 to the receiver D, the pipes 2 6 thus forming liquid-collecting pipesconnected to the bottom of the coils.

It will be understood that while I have shown only two coils thisnumbermay be increased as desired, other coils then being added abovethe coil A, the gas then lpassing successively to the 'top of the uppercoils, and the spray-pipe B being located above the top coil of theseries, each ofthe coils except the travel astheyv form to theirpoint'o'f exit in top coil being preferably provided with a IOO'departing from the invention, and the cooling liquid may be appliedotherwise than by sprinkling on the top of the upper coil.

What I claim is- 1. In a condenser, the combination, with a series ofcoils arranged one above another and a single supply forcondensing-Water arranged above all the coils of the series so that theWater drips Jfrom coil to coil successively; of an inlet-pipe forammonia-gas connected to the top convolution of the bottom coil,connections between the bottoni convolutions of the said coils and thetop convolutions of the coils next above them in the series one'afteranother, and liquid-collecting pipes connected to the bottomconvolutions of said coils.

2. In a condenser, the combination, with a series of similar singlecoils arranged one above another and exposed to the atmosphere,

and a single supply for condcnsiIig-water zn'- ranged above all thecoils of the sorles so that thcwater drips from coil to collsuccessively;

of an inlet-pipe for annnonia-gas connected to GARLETON lV. NASON.
